Amazon Intern Software Engineer interview questions

Applied online . Got interview call on-campus after a week or so, Two back to back interviews of 45 minutes. First interview was by the university alumni . He asked the following questions . 1) Find the maximum sum subset for a given array . 2) Given two sorted arrays find the elements of the first array not present in the second. 3) Given a N*N array where N is even such as 4, 8 and so on . Print the array from the center. a= [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16] the output should be [6 10 12 7 3 2 1 5 9 13 14 15 16 12 8 4 ] . The interviewer gave me sufficient time to think about the problem and then gave some tips as thou how it can be solved . Then he told me to write the code . Second round of interview was very easy. the interviewer asked various question on the scenarios faced by amazon.

Just had my first round of phone screening interview. First interviewer asked programming related questions and asked me to code. The second one basically asked higher level and open ended technical questions. Both used an online code typing and sharing tool.
